Hello Alan, I recollect over long periods the best times at 136kHz were either just after sunset, or just before dawn<<< Talking about "just after sunset, or just before dawn" is not very precise as

I think you have be carefull interpreting this paper....the term "LF" would seem to refer to low HF though my German is not good enough to understand it fully. The ionospheric effects at these higher

Hi Stefan, there has been some geomagnetic activity that might account for the poor conditions you saw. Yes poor propagation also affects the noise level at this time of year because a lot of the noi

Hi Alan/all - I can confirm (very) poor Northern Auroral crossing paths at HF to LF as seen from here in Alaska at the moment - pesky Protons really wreck havoc at this geo mag latitude. Im not seein

Dear Doug, LF Group, I was under the (admittedly simplistic) understanding that, the lower one goes in frequency, the more the signal propagates via groundwave. In amateur experience, communications
